2 Claims. 1

This invention relates to railroad tie construction and it aims to provide one in which the danger of low points and spreading rails is greatly reduced in order to enhance safety.

More specifically, it is aimed to provide a structure which has blocks of concrete suitably reinforced, connected by a tie rod, and which blocks in turn resiliently mount a tie member of channel form interfitted with the blocks.

The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment.

In said drawings- Figure 1 is a plan view of a tie structure according to the invention, rails being suggested in dot-dash lines;

Figure 2 is a view in elevation of the parts of Figure 1;

Figure 3 is an approximately central longitudinal sectional view through the structure of Figure 1;

Figure 4 is a horizontal section taken on the line 44 of Figure 3;

Figure 5 is an end elevation of the structure of Figure 1; and

Figure 6 is a vertical section taken on line E6 of Figure 2.

Referring specifically to the drawings wherein like reference characters designate like or similar parts, my improved tie construction comprises a pair of concrete blocks as shown at Ill. These blocks are suitably mounted for support on the ballast ll of the road bed and they are preferably reinforced by metallic elements as at I2, to minimize danger of fracture.

The blocks I are preferably connected to-- gether by a tie rod i3 of inverted U-form whose legs l4 pass through staples l anchored to the inner side of the blocks 10.

Disposed across the blocks is a tie member It generally of channel iron form and preferably of steel.

The blocks ID have central wells I! in which are seated pairs of concentric coil spring I8 and IS, the springs extending above the blocks and spring I!) directly engaging and resiliently supporting the tie member I6. Springs [9 surround centering studs 20 which are resiliently supported by 5 the springs l8 and which have depending projec- 2 tions 2| fitted within the springs i8. The studs 20 may be welded in place to the tie member [6.

The end walls of the tie member it have downward extensions 22 which are slidably disposed in staples or guides 23 anchored to the end walls of blocks It).

It will be realized that the tie structure disclosed is used in place of the usual wooden or other form to support and mount track rails suggested in dotted lines as at 24, and which rails may be secured to the tie members in any suitable manner. It will also be realized, that the rails are resiliently supported and that the springs not only resiliently support the tie member but also function to minimize danger of shock and fracture to the concrete tie blocks.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

I claim as my invention:

1. A structure of the class described comprising tie blocks, a tie rod, staples on said blocks, engaged by the tie rod, a second staple on said blocks, a tie member having depending end extensions engaging the second staples, and resilient means supporting the tie member from said blocks.

2. A structure of the class described comprising tie blocks, a tie rod, staples on said blocks, engaged by the tie rod, a second staple on said blocks, a tie member having depending end extensions engaging the second staples, and resilient means supporting the tie member from said blocks, said resilient means comprising concentrio springs, the blocks having recesses abutting said springs, studs depending from the tie member and resting on the innermost springs, and being surrounded by the outermost springs.
